[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] like Figures 1 to 6 As shown, this embodiment provides a cleaning machine to solve the problem that the cleaning machine is difficult to assemble and the rotating hole is prone to water leakage, which may cause damage to the driver 500 or even fire, threatening the personal safety of users. The cleaning machine includes a housing 100, a spray arm 200, a moving part 300, a transmission mechanism 400 and a driver 500. The shell 100 has a cleaning chamber; the spray arm 200 is located in the cleaning chamber and is provided with a spray hole 210, and the spray arm 200 extends along a first direction X of the cleaning chamber; the moving member 300 extends along a second direction Y that is at an angle to the first direction X of the cleaning chamber, and is arranged to be able to move along its own extension direction, the spray arm 200 is assembled on the moving member 300, and can synchronously reciprocate with the moving member 300 relative to the cleaning chamber in the second direction Y; the transmission mechanism 400 has a main rotor 410 and a secondary rotor 420, the main rotor 410 and the secondary rotor 420 are magnetically matched to form a magnetic coupling connector, the main rotor 410 is located outside the cleaning chamber, and the secondary rotor 420 is rotatably arranged inside the cleaning chamber and is transmission-connected to the moving member 300; the driver 500 is arranged outside the cleaning chamber and is drivingly connected to the main rotor 410.

[0041] The driver 500 of the cleaning machine drives the moving part 300 to move through the transmission mechanism 400, thereby driving the spray arm 200 to move, wherein the transmission mechanism 400 includes a main rotor 410 and a secondary rotor 420 forming a magnetic coupling connector, and the main rotor 410 is connected to the driver 500 outside the cleaning chamber, and the secondary rotor 420 is connected to the transmission part inside the cleaning chamber, so that the housing 100 does not need to be provided with a hole structure connecting the cleaning chamber with the outside, nor does it need to be provided with a sealing mechanism, and there is no problem of leakage due to aging of the sealing structure, thereby avoiding damage to the driver 500 or even fire caused by leakage, and ensuring the personal safety of the user. In addition, during installation, it is only necessary to install the secondary rotor 420 and the main rotor 410 on both sides of the inside and outside of the cleaning chamber to realize the transmission connection between the driver 500 and the moving part 300, which has a simple structure and high assembly efficiency.

[0042] Combination Figure 5 As shown, the cleaning machine further includes a base 110, the base 110 is disposed in the cleaning chamber, the transmission mechanism 400 further includes a rotating shaft 430, the lower end of the rotating shaft 430 is rotatably disposed on the base 110, and the secondary rotor 420 is coaxially connected to the rotating shaft 430. The above arrangement connects the secondary rotor 420 to the base 110 through the rotating shaft 430, which is conducive to simplifying the structure of the secondary rotor 420 and reducing production costs.

[0043] Combination Figure 6 As shown, in order to prevent the displacement of the rotating shaft 430, a limiting portion is provided on the circumference of the rotating shaft 430, and the transmission mechanism 400 also includes at least two crimping members 440, at least two crimping members 440 are arranged on the base 110, and at least two crimping members 440 are arranged at intervals along the circumference of the rotating shaft 430 to limit the lateral displacement of the rotating shaft 430, and the crimping end of the crimping member 440 is arranged on the upper side of the limiting portion to limit the upward movement of the rotating shaft 430.

[0044] The rotating shaft 430 includes a shaft body 431 and a disc-shaped stopper 432 disposed at the lower end of the shaft body 431. The stopper 432 has an outer diameter greater than that of the shaft body 431. The bottom of the stopper 432 abuts against the base 110. The top wall of the stopper 432 forms a stopper. The crimping ends of each crimping member 440 are disposed on the upper side of the top wall of the stopper 432. The stopper 432 has a larger outer diameter, so that the contact area between the rotating shaft 430 and the base 110 is larger, thereby ensuring the stability of the rotation process.

[0045] The crimping member 440 includes a fixed plate 441, a crimping plate 442, and a connecting plate 443 disposed between the fixed plate 441 and the crimping plate 442. The fixed plate 441 and the crimping plate 442 are spaced apart along the axial direction of the rotating shaft 430, and the fixed plate 441 and the crimping plate 442 are respectively located on both sides of the connecting plate 443 along the axial direction perpendicular to the rotating shaft 430. The fixed plate 441 is mounted on the base 110, and the crimping plate 442 forms a crimping end. Among them, at least two connecting plates 443 are spaced apart on the circumferential side of the limit block 432 to limit the lateral displacement of the rotating shaft 430. Among them, it should be noted that the axial direction of the rotating shaft 430 is parallel to the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0046] Among them, there are two crimping parts 440, and the crimping parts 440 are a partial rotating body structure, that is, the projection of the crimping parts 440 on the plane perpendicular to the axis of the rotating shaft 430 is fan-shaped. The two crimping parts 440 can be spliced ​​to form a rotating body structure to improve the installation efficiency of the crimping parts 440.

[0047] Of course, the limiting portion may also be formed in other ways. For example, an annular groove is provided on the circumference of the rotating shaft 430, and the lower side wall of the annular groove forms the limiting portion. The crimping end of the crimping piece 440 is inserted into the annular groove.

[0048] The driver 500 is a servo motor, which is fixed to the housing 100, and its output end is coaxially fixedly connected to the main rotor 410. This arrangement facilitates the installation between the main rotor 410 and the servo motor, and improves assembly efficiency.

[0049] Combination Figure 4 and Figure 5As shown, a wastewater collection tank 120 is provided in the middle area of ​​the cleaning chamber to complete the wastewater collection tank 120 of the cleaning process. Considering that the main rotor 410 and the secondary rotor 420 need to be coaxially arranged, and the output shaft of the driver 500 and the main rotor 410 are coaxially arranged, when the secondary rotor 420 is located in the middle area, the driver 500 will interfere with the wastewater collection tank 120, resulting in the wastewater collection tank 120 needing to be provided with an avoidance structure and becoming complicated, which makes cleaning difficult and affects the user experience. To this end, the transmission mechanism 400 also includes a first transmission member 450 and a second transmission member 460 that are transmission-connected. The first transmission member 450 and the second transmission member 460 are both arranged to rotate around their own axes. The second transmission member 460 is transmission-connected to the moving member 300, and the first transmission member 450 is coaxially fixed to the secondary rotor 420. The above arrangement ensures that even if the second transmission member 460 is disposed in the middle area of ​​the cleaning chamber and the first transmission member 450 is located beside the second transmission member 460, the driver 500 coaxial with the first transmission member 450 is naturally away from the middle area of ​​the cleaning chamber, thereby away from the wastewater collection tank 120, thereby ensuring the integrity of the wastewater collection tank 120 and facilitating subsequent cleaning to improve the user experience.

[0050] The first transmission member 450 and the second transmission member 460 both include transmission wheels, that is, the second transmission member 460 includes a first transmission wheel, and the second transmission member 460 includes a second transmission wheel 461. The transmission mechanism 400 also includes a transmission belt 470, and the transmission belt 470 is sequentially wound between the first transmission wheel and the second transmission wheel 461. The cooperation of the two transmission wheels and the transmission belt 470 can realize the transmission of power, and the structure is simple and the cost is low. Among them, the first transmission member 450 and the second transmission member 460 are arranged at intervals along the first direction X to avoid interference between the moving member 300 and the transmission belt 470.

[0051] To ensure accurate control of the position of the moving member 300, the transmission wheel is a synchronous pulley with a toothed structure on the peripheral wall, and the transmission belt 470 is a synchronous belt. The inner side of the corresponding synchronous belt has a toothed portion that can be adapted to both synchronous pulleys, and the transmission belt 470 is meshed with the synchronous pulley. The cooperation of the synchronous belt and the synchronous pulley can accurately complete the transmission of the output speed of the driver 500, so that the speed of the second transmission member 460 can be accurately controlled according to the speed of the output end of the driver 500, and then the moving position of the moving member 300 can be accurately controlled.

[0052] The second transmission member 460 comprises a gear 462, which is coaxially connected with the second transmission wheel 461 and can rotate synchronously with the second transmission wheel 461, and the mobile member 300 is a rack, and the gear 462 is meshed with the rack. The meshing transmission of the gear 462 and the rack can effectively ensure the transmission accuracy, thereby accurately controlling the position of the rack. Another exemplary embodiment, the second transmission member 460 is a roller, which is coaxially connected with the second transmission wheel 461 and can rotate synchronously with the second transmission wheel 461, and the peripheral wall of the roller and the mobile member 300 directly roll and cooperate. For improving the reliability of transmission, the peripheral sleeve of the roller is provided with a rubber sleeve to increase the friction between the roller and the mobile member 300, thereby realizing the effective transmission of power.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
